TS ISO 11323

TS ISO 11323 is a terminology standard for iron ore and direct reduced iron ore. It establishes the terms and definitions used in sampling, sample preparation and division, moisture determination, particle size distribution analysis, and physical testing, giving laboratories, operators, and trading partners a common technical language for describing these materials.

How the vocabulary supports ore handling and testing

The standard addresses the language used for two related but distinct materials: iron ore and direct reduced iron ore. Iron ore is the raw feedstock for ironmaking, while direct reduced iron ore is material that has already undergone a direct reduction route and may behave differently in downstream handling and testing. Because particle size, moisture sensitivity, representativeness of samples, and physical behavior can all influence results, precise terminology matters for consistent interpretation and comparison of data.

General technical context behind the listed test areas

In general practice, sampling is the process of obtaining a smaller portion that represents a larger ore lot; sample preparation and division then reduce and split that portion into testable subsamples. Moisture analysis relates to water content, which affects transport, storage, and process performance. Particle size distribution analysis describes how the material is distributed across coarse and fine fractions, while physical testing typically concerns properties such as strength, flow behavior, or tendency to break down. By defining the vocabulary for these activities, the standard helps align communication across testing and production environments.
